Abstract

There is provided a novel polymer, a composition containing the polymer, and a novel adhesive composition containing the polymer from which a cured film having desired properties is obtained. A polymer comprising a structural unit of Formula (1): wherein Q is a bivalent group, R 1 is a C 1-10 alkylene group, a C 2-10 alkenylene group or C 2-10 alkynylene group, a C 6-14 arylene group, a C 4-10 cyclic alkylene group, etc., or a polymer comprising a structural unit of Formula (6): wherein Q 4 is an allyl group, a vinyl group, an epoxy group, or a glycidyl group, and R 5 is a bivalent organic group having a main chain containing only carbon atom or at least one of oxygen atom, nitrogen atom and sulfur atom in addition to carbon atom, a composition comprising the polymer, and an adhesive composition comprising the polymer and a solvent.

Claims (21)
